          Abstract

          In a recent article, Chang et al. proposed a quantum secure direct communication protocol using single photons (Chinese Sci Bull, 58: 4571-4576). The protocol is equipped with authentication. In this article we present a novel attack on the protocol that can determine the secret key which is already shared between Alice and Bob.
